NanoFATE has been conceived to fill knowledge and methodological gaps currently impeding sound assessment of environmental risks posed by engineered nanoparticles (ENPs). Our vision is to assess environmental ENP fate and risk in example high-volume products for which recycling is not an option, namely; fuel additive, personal care and antibacterial products. Two market ENPs from each product (CeO2, ZnO, Ag of varying size, surface and core chemistries) will be followed through their post-production life cycles i.e. from environmental entry as “spent product”, through waste treatment to their final fates and potential toxic effects. This will test the applicability of current fate and risk assessment methods and identify improvements required for assessment of ENPs at an early stage.
Laboratory of Nanostructures for Photonics and Nanomedicine IHPP PAS is an expert in the synthesis of doped nanoparticles with small size distribution using microwave technology solvothermal synthesis (MSS). MSS technology allows precise control parameters of nanoparticle synthesis such as reaction time, temperature and pressure. Laboratory Nanostructures for Photonics and Nanomedicine IHPP PAS is responsible for providing the doped zinc oxide for project NanoFATE. We obtain the zinc oxide doped with cobalt ions with controlled content of dopant and particle size distribution in solvothermal synthesis which can be expressed as follows:
(CH3CO2) 2Zn + y(CH3CO2) 2Co → Zn(1-x) CoxO

Synthesis of nano-zinc oxide doped with cobalt take place in solution of ethylene glycol during 25 minutes. Specific surface doped ZnO is 30-50 m2/g and crystallites size are in a range from 20 to 50 nm.
